I don't know if it is losing its spin. It's possible, but I wonder whether it may have something to do with the wave slowing down. If you look at the visible loop, 97L does not seem to be moving as fast as it was a few hours ago. Just my opinion, for what it's worth.

BTW, there's a recon planned for this system now.
